Answer:
For differents τ:
τ = 1000 Å → B = 0.11°
τ = 750 Å → B = 0.15°
τ = 250 Å → B = 0.44°
For differents Θ:
Θ = 10° → B = 0.31°
Θ = 45° → B = 0.44°
Θ = 80° → B = 1.78°
Explanation:
To factor B is related to the size of particles, Θ, and λ by the Scherrer equation:
<em>where τ: size of the particles, λ: is the wavelenght of the X-Rays, B: is the line broadening at half the maximum intensity, Θ: angle of incidence and K: is a shape factor with typical value of 0.9 </em>
Now, factor B for the diameter of the particles (τ) is:
τ = 1000 Å:
τ = 750 Å:
τ = 250 Å:
For τ = 250 Å, factor B for angles of incidence is:
Θ = 10°:
Θ = 45°:
B = 0.438°
Θ = 80°:
